ER4047 Tig Vuam

1. Daim Ntawv Thov Kev Sau Npe

Thawj Welded Khoom: Siv tau rau vuam 6000-koob aluminium alloys (piv txwv li 6061, 6063). Nws kuj tseem siv tau rau brazing lossis kho cov khoom siv txhuas.

Cov Kev Siv Raug Raug: Kev sib txuas ntawm txhuas alloy qauv xws li lub tsev ua haujlwm, chaw kho tsheb, thiab cov hlab ntsha {{} siab} kev pom zoo weld.

2. Ua ntej -} vuam npaj

2.1 workpiece preprocessing

Ua tib zoo ntxuav lub vuam qhov chaw vuam: Siv tus pas hlau stainless hlau los tshem tawm cov neeg sawv cev oxide, lossis siv tshuaj tua kab kom tshem tawm cov roj stains thiab impurities. Xyuas kom cov nplaim hluav taws xob yog cov kua oxide dawb thiab cov khoom paug (cov kua oxide tuaj yeem ua rau muaj qhov tsis xws luag thiab tsis muaj fusion).

Kev tswj hwm loj: ER4047 muaj cov fluidity zoo thiab tuaj yeem haum cov khoob ntawm 0.5 {}} 2mm. Rau ntau dhau qhov khoob, ntau dua vuam yog qhov yuav tsum tau ua rau txhaws.

2.2 khoom thiab xaiv cov kev xaiv

Lub Hwj Chim Source: Siv IbAC - tig (hloov tam sim no lig) vuam tshuabCov. Lub "Cathodic tu" cov nyhuv ntawm lwm txoj kev tam sim no pab tshem tawm cov yeeb yaj kiab oxide ntawm txhuas nto.

Tungsten Electrode: Xaiv cov ntshiab tungsten (WP) lossis zirconiated tungsten (WZR) electrodes. Lub taub diam yog txiav txim siab los ntawm vuam tam sim no (piv txwv li, 1.6-3.2mm), thiab cov lus qhia yuav tsum tau nyob rau hauv ib tug ncej ntawm kwv yees li 60 degree).

Kev thaiv cov roj: Siv cov ntshiab AgN (AR) nrog kev coj dawb huv ntau dua lossis sib npaug rau 99.99%. Tus nqi txaus yog feem ntau yog 10-20L / min (kho raws li vuam tam sim no thiab cua nrawm; nws tuaj yeem raug txo qis nyob rau hauv cov kev mob windproof).

4. Cov Txheej Txheem Ua Haujlwm

4.1 Arc Pib thiab Kev Txiav

ARC Pib: Sivhigh - zaus arc pib(Zam kev tiv toj ARC pib tiv thaiv tungsten Electrode). Tom qab Arc Ignition, tswj lub arc ruaj khov rau 1-2 feeb. Thaum lub hauv paus hlau yog ib nrab melted los ua ib lub pas dej weld, pub vuam hlau.

ARC txiav tsis taus: maj mam txo qhov tam sim no (lossis siv cov kab ke tsis zoo tam sim no), thiab sau lub pas dej weld nrog cov xaim hluav taws xob kom txog thaum nws ua tiav kom tsis txhob muaj cov kab nrib pleb.

4.2 Cov Qauv Siv Hlau

Pub cov hlau los ntawm sab xub ntiag lossis sab ntawm lub pas dej weld, ntawm kaum sab xis ntawm 15-30℃nrog lub workpiece. Zam kev sib cuag ncaj qha nrog lub tungsten electrode (tiv thaiv kev sib tsoo tungsten tsis huv ntawm weld).

Saib xyuas cov hlau cov hlau pub ceev kom ntseeg tau tias tag nrho sau ntawm Weld Pas thiab Weld tsim.

4.3 Vuam kaum

Khaws lub teeb ci ntsa hauv lub kaum ntawm kwv yees li 70-80℃nrog lub workpiece. Mloog cov arc ntawm lub pas dej weld kom tsis txhob muaj cua sov ntau thiab tom qab cov khoom lag luam hauv paus tom qab.

5. Kev ceev faj

5.1 Kev Tiv Thaiv Kev Tiv Thaiv

Porosity: Ua kom muaj kev tiv thaiv cov pa roj txaus thiab huv si los tiv thaiv cua los ntawm kev nkag mus hauv Weld pas dej thaum vuam.

Nrig: Tswj cov lus tawm thaum tshav kub kub (tsis txhob overheating). Kom tuab daim hlau, siv multip -}}} dhau vuam thiab ua kom lub interpet kub hauv qab 150 degree.

Tungsten Electrode chav paug: yog tias xaim kov lub tungsten electrode, nres vuam thiab tswj hwm cov electrode. Txwv tsis pub, kev suav nrog yuav tshwm sim hauv Weld.

5.2 Kev Tiv Thaiv Kev Nyab Xeeb Kev Nyab Xeeb

Hnav lub kaus mom hlau tua hluav taws tshwj xeeb (UV {{{} {{{{{{{1} {{2} - retardant khaub ncaws. Ua kom muaj kev puas tsuaj zoo (los tiv thaiv kev sib txuam).

Los ntawm kev ua raws li cov kauj ruam saum toj no, koj tuaj yeem siv cov hmoov av los ntawm ER4047 xaim kom tau txhuas welds nrog kev tsim zoo thiab ruaj khov kho cov khoom. Hauv kev xyaum, cov tsis muaj zog yuav tsum zoo-}}}}}}}}}}} }n dickness thiab khoom siv yam ntxwv. Nws raug nquahu kom ua txoj kev kuaj vuam ntawm qhov ntsuas ntsuas ua ntej.
